REGISTERIATTACH M EN T FOR TELEPHONES.

SPECIFICATION forming part of Letters Patent No. 355,745, dated January11, 1887.

Application filed May 17, 1886. Serial No. 202.412; (No model.)

To all whom it may-concern:

Be it known that 1, CHARLES WITTENBERG, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented a new and useful Improvement in Register Attachments forTelephones, of which the following is a specification.

My invention relates to the c0mbination, in an improved manner, of aregistering mechanism with the switch-lever and receiversupport of atelephone apparatus for the purpose of recording the movements of saidswitchever.

The object of my improvement is to provide means whereby the registermay be operated by the actof hanging the receiver upon the switch-lever,and whereby the switchlever may be operated independently of theregister by the hand of the operator, all as hereinafter fully setforth.

The accompanying drawings illustrate my invention.

Figure 1 represents a front elevation of a Bell telephone case with myattachment. Fig. 2 represents the same when the receivingtelephone hasbeen removed. Fig. 3 is an elevation showing the relative positions ofthe switch-lever and the actuatinglever of the register when theswitch-lever'is depressed by the hand of the operator. Fig. 4 is a sideelevation showing the register in section and the fork of theswitch-lever removed. Fig; 5 is a detached partial plan of theactuating-lever of the register.

A is the well-known automatic switch-lever,

- by means of which the telephone is connected with the line-circuit.The projecting end of said lever is forked to receive and support theand the fork of the switch-lever.

- lever in such a manner that the said actuatinglever is raised by theupward movement of the switch-lever. Y

F is a forked bracket, corresponding in size and shape to the forkedportion of the s witch- 'lever, and adapted, like said lever, toreceive.

said telephone is taken down for operation, the switch-lever is drawnupby a spring to the position shown in Fig. 2, thus carrying bracket F andthe register-actuating lever up also. By this movement of the lever thesignal-bells are disconnected from the line-circuit and the telephone isconnected therewith. When the receiver is hung up again, bracket F, theregister-actuating lever D, and the switch-lever are thereby drawndownward simultaneously, and the register is carried forward one point,thus indicating the number of times that the telephone is used.

When the It often occurs that it becomes necessary to signal the centralstation of the telephone system the second time before communicationbetween two stations is established, and to do this the switch-levermust be brought down again. istration of this second movement oftheswitchlever-the arrangement is such that the said lever, when pulleddown separately by the For the purpose of avoiding the reghand of theoperator, moves away from and does not engage the actuating-lever of theregister, as clearly shown in Figs. 3 and 4:.

said receiver, the register having its actuatlever without moving theactuating'lever, for ing-lever adapted to engage the switch-lever, thepurpose specified. and the forked bracket F, adapted also to hold thereceiver and hinged to said actuating- 5 lever, substantially as shownand described, Witnesses:

whereby the free edge of said bracket is H. P. HOOD, adapted to followthe movements of the switch- V. M. HOOD.
